The invention discloses an ultra-high field strength, ultra-short pulse, and narrow-band microwave radiation field measurement system, which consists of sequentially connected broadband double-ridge horn antennas, microwave broadband attenuators, high-speed microwave detectors, and high-speed digital oscilloscopes. The ridge horn antenna is connected to the microwave broadband attenuator by a low-loss RF coaxial cable. The invention also provides a method for measuring ultra-high field strength, ultra-short pulse, and narrow-band microwave radiation field. The invention adopts the broadband double-ridge horn antenna as the front-end field receiving probe, and has a wide application range; adopts the low-loss radio frequency coaxial cable and the microwave broadband attenuator to transmit the high-power microwave pulse signal received by the front-end broadband double-ridge horn antenna And attenuation, not only safe, but also improve the dynamic range of measurement, with accuracy and flexibility. After the microwave pulse signal is detected by a high-speed microwave detector, parameters such as the amplitude, rise time, and pulse width of the signal can be measured by an oscilloscope.
